Hello there!
We would practically divide both 16 and 3.We would want to find out how many 3's go into 16.
Let's see. 3+3=6+3=9+3=12+3=15
There are five 3's.
This would help us and understand that 5 is our main big number.
We have 1 left. We would divide this by 3, and your result would be . . .
[tex]\boxed{\bf{ 5\frac{1}{3} }}[/tex]
I hope this helps you!
